Specification of Letters Patent.

Application filed April 22, 1914. Serial No. 833,768.

, Be it known that 1, Oscar: R. MANVILLE,

a citizcn iof the United States, residingat and State of Missouri, have invented a new and useful Draft Attachment for Vehicles, of which the following is a specification.

This invention relates to improvements in theidraftportions of vehicles and more particularly to awagoni tongue and accompanying parts. it w The object of the present invention is to provide :a vehicle. tongue formed of metal and so constructed as to be light in weight and cheap to manufacture so as to compete with tongues formed of other materials. A further object is to provide a vehicle tongue and swingletrees therefor formed of spaced angle iron members which will withstand'hard usage and will not deteriorate in any marked degree with age. u

Anotherobject is to improve generally andenhance. the utility, of those devices to which thepresent invention appertains, Niththe foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the detailsof construction hereinafter described and cla1med,,1t being understood that changes in the precise embodiment of In the drawings accompanying this specification and forming a part thereof, the preferred embodlment of my invention is illustrated, in which Figure 1 is a top plan view of the vehicle tongue and accompanying parts. Fig. 2 is a view in side elevation thereof. Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 2. Fig. aisacross sectional view taken on the line 4:-.el of Fig. 1. Fig. 5 is'a top plan view of one portion of the whiliietree illustrating the same as being applied to the shafts of a vehicle. Fig. (3 is a cross. sectional view taken on the line 6-6 of Fig. 1. Fig. 7 is a cross sectional View taken on the line 77 of Fig. 1. 7

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, the tongue proper, 5, is formed by two angle members 6 and 7 secured together and held in fixed relation by the spacing blocks 8.

Patenteddan.12,191l5i Suitable'rivets 9 project through the side I walls of the angle members and the spacing blocks, to thus rigidly hold the angle members in the form of a channel bar.

The rear extremities of the angle members are outwardly curved as at 11. The extremities of the angle bars are secured to the curved bridge member .12 by suitable means 13. The'fopposite extremities of the angle bars taper't'o a point over whichextends a cap 14: and from-which projects. a rim 15. A tie or brace rod 16 projects through the front extremity of the cap 14: and is provided with the tightening nut 17 thereon. The tie'rod isin the nature of a truss or brace bar and projects rearwardly and centrally beneath the angle bars, passing through. suitable grooves 18 in the spacing blocks and projectsabove the top surface of the rear spacing block 19. The rear eX- tremity of the truss rod is provided with the eye 20 through which a pivot bolt 21 extends, to securely anchor this extremity of the strut bar in place and allowing the requisite tension to be exerted within the bar by adjusting the nut 17.

A: pair of connecting rods 22 are rigidly I secured at 23 to the bridge member 12, and project therebeyond to form the attaching arms 24 through which the apertures 25 ex-y tend... The apertures 25 are provided for the rec ption' of bolts or other securing means ,whereby thetongue is secured to the vehicle.

The front extremities 26 of the connecting rods. are rigidly secured to the angle members 6 and 7 as will be clear by referring to Fig. 2.

The rear spacing block 19 through which the pivot bolt 21 extends holds the angle members in spaced relation at this point and directly above the same is mounted the doubletree 27. The doubletree is also formed of the angle members 29 which are held in spaced relation by suitable blocks 30; The swingletrees 31 are also formed of spaced angle members'32 and are provided with spacing blocks The usual and suitable clamp 3-1 extends through the swingle and double trees and provides for their pivotal securement. Each swingletree as illustrated in Fig. 5 comprises the central spacing block 33. and the end blocks 34.

acting in conjunction with the rotating latch members 36' are adapted to lock or? secure the traces to the swingletrees in such manner as to prevent their accidental de-M,

tachment. In orderto strengthen the bolt 21, the bracket 37 is provided, the same being ofiset as at 38, allowing it torigidly engage the upper extremity ofthe bolt 21 and the rear bridge member 12 without interfering with the movement of the Whittle tree. The forward extremity of the bracket 37 is upwardly curled as at 39, allowing a strap or allied flexible member to be secured thereto. 7 i i Having thus fully described my invention, what I claim is 1. An article of the class described, comprising apair of angle members, means secured thereto and holding the same in spaced. relation, a curved bridge member rigidly secured to the extremities of said angle members, connecting rods secured to said an'gle members and the said bridge member, said connecting rods projecting rearwaii'dly and forming attaching arms, and a truss rod extending longitudinally beneath the angle members and bracing the 2. An article of the class prising a pair ofangle members, means secured thereto and holding the same in spaced relation, a curved, bridge member rigidly secured to the extremities of said angle members, connecting rods secured to said angle members and the, said bridge member, said connecting rods projecting rearward-1y and forming attaching .arms, a truss rod extending beneath said angle members contacting'with the lower surfaces of 7 Copies of this batent may be obtained for described, comsaidi'spacing means, said truss rod proj'ect ing beyond the front extremities ofsai tioned 'upon 'the front extremitycf said truss rod,'engagi'ng the frontextremity of "angle members, and tightening means posithe angle members,adapted to adjust the members for the attachment of the same to a vehicle, a cap positionedupon the front extremities of theangle members, "and a truss rod projecting through thesaid cap, passing beneath and contactingwith the spacing blocks and anchored to the rear portions of said anglemembers, and means positioned upon the truss rod beyondand' contacting withsaid cap for the adjustment of the strutbar tension.

41A vehicletongue comprising elongated members, means disposed therebetwe'en and secured thereto, holding the same in spaced relation, means. secured to and projecting from the sides of the said members adapted to secure the same to a vehicle, and a truss rod extending axially beneath the'saidl elongated; members and contacting with the said spacing means thereof and bracing the elon gated i'nembers in vertical plane.

In testimony thatl claim the foregoing as my own, have hereto affixed my sigma ture in the presence of two witnesses.
